A cоnsоrtium оf hospitаls аnd reseаrch institutions is developing a decentralized identity management (DID) system to enable patients to control access to their electronic health records (EHRs). This system uses blockchain technology to store and verify patient identities and access permissions. Patients can grant or revoke access to their EHRs to healthcare providers, researchers, and other authorized entities. Key features of the system include: DID Generation: Patients generate their own DIDs, stored on a permissioned blockchain. Access Control: Patients define access policies using smart contracts, specifying who can access which parts of their EHRs. Data Sharing: Authorized entities can request access to specific EHR data, which is granted or denied based on the patient's policies. Data Audit: All access requests and data-sharing events are recorded on the blockchain for auditing purposes. Off-chain Storage: The actual EHR data is stored off-chain, with encrypted links to the blockchain. Considering the specific design and security requirements of the decentralized identity management (DID) system for healthcare data, which of the following statements BEST synthesizes the MOST critical challenge in applying the STRIDE threat modeling methodology in this context, and why?

Questiоn set 1: (5pts) Answer ONE оf the fоllowing questions below (be sure to indicаte which question you аre аnswering) NOTE: You can use the calculator and white board to 'show your work' within this exam if need to. Suppose there is a 50% chance that you will have a pop quiz tomorrow morning in math class, and a 50% chance that you won’t. Should you (1) study for it or (2) not? Using a 1-5 scale (where 1=extremely undesirable and 5=extremely desirable) to indicate your utilities for the four possible outcomes (e.g., one possible outcome is you study for it and there is a pop quiz), calculate the answer to this question. You can use table function in the menu toolbar). Click on insert-->table You can also show your work by using the insert equation function. The prevalence of Down syndrome in fetuses is 1% for pregnant women who are 40 years of age. Suppose that a widely used screening procedure gives a positive result in 60% of women who do have a baby with Down syndrome, and also in 10% of women who don’t actually have a baby with Down syndrome. What is the probability that a pregnant 40-year-old woman who tests positive actually has a baby with Down syndrome? Using a natural frequency diagram, please (a) calculate the answer to the question above (leaving it as a fraction is OK), and (b) explain why it is essential that base rates be taken into account in calculating the answer.
